J. o. MAYBEEEY'AND c. N. MAYBEEEY, 0E WHITEy EooKJLLiNors IMPROVEMENT lN HARvEsTlNe-'MAGHINEa Specification forming part of Letters Patent No. 33,748, dated lNovember 19, 1561K.

. C. N. MAYBEREY, of White Rock, in the county of Ogle, and State of Illinois, have invented a new and Improved Harvester; and we' do hereby declare that the following is a.

full, clear, and exact description of the same, reference being had to the annexed drawings, makinga part of this speciiication, in which- Figure l is a side sectional view of our invention, taken in the line a: x, Fig. 3; Fig. 2, a detached view of the endless apron pertaining to the same; Fig. 3, a horizontal section ofthe same, taken in the line y y, Fig. 1; Fig'. 4, a detached view of a portion of the back bar of the frame of the machine.

Similar letters of referenceA indicate corresponding parts in the several figures.

This invention relates to certain improvements in that class 'of harvesters in which` the team is placed behind the frame of the machine and an endless apron employed for discharging the cut grain.

The object of the invention is to balance the machine more evenly than hitherto, cause the same to work steadier or with less vibration, to equalize the draft, render the cutting` device capable of being raised and lowered with facility, and enable the discharging-apronV to be adjusted to suit receiving-wagons o f different heights.

To enable those skilled in the art to fully understand and construct our invention, we will proceed to describe it.

A represents the frame of the machine, which is of rectangular form, and is supported by wheels B C, B being the driving-wheel and placed at one end of the frame.

D is the draft-pole, which is attached at its front end to the frame A at a point in line with the axle of the wheel B, or nearly so, the pole being attached to the frame by joints a a. In order to admit of this attachment, the back rail, b, of the frame A is divided and a space left between the ends for the pole toY pass through, and the two. parts of said rail b are connected by a metal plate or bar, E, so 'bent as to admit of an upand`down play of the frame A. (See Fig. 4.) On the top of the bar E there is placed a pulley, c, over which a rope or chain, F7 passes, the front end of which is attached to pole D immediately underneath bar E, said rope or chain also passing underneath a'guide-pulley, d, attached to the draft-pole and connected at its back lendto a treadle- Wheel, G, on the draft-pole, the wheel Gbeing kept in position or prevented from casually turning by means of a stop, e, arranged in any proper way. `The 'back end of the draftpole D is supported by acaster-wheel, H. (Shown in Figs. l and 8.) i

To the front end of the frame A the sickle I is attached, said sickle being of the ordinary reciprocating kind, and operated from the wheel B in the ordinary way.

From the above description it will be, seen that the sickle may be raised and lowered with the greatest facility by simply. turning the wheel G, and the sickle retained at any deA sired height. The frame being nearly balianced-onthe axle of wheels B C, it may be adjusted with the slightest effort of the driver, whose seat J is directly back of wheelG. This arrangement also admits ofthe ready -turning of the machine and renders' the draft easy or light.

On the front part of the' frame Aan endless apron, K, is placed. This apron, directly back of the sickle I, has a horizontal position, or is 'in the same plane with the frame; but at the end near the wheel B, it is inclined, in order that it may convey the cut grain into a wagon at the side of the machine. This apron works l between suitable guides, f f, and is arranged in the usual way, with the exceptionof the inclined part, which has the upper part, L, of its frame connected to the lower part, M, by joints g in standards g. In using the machine the frame L lVI is rst adj usted at any suitable height in the standards g, its upper portion being supported by cords g2, as shown in Fig. 2. The upper part, L, of the frame, by reason of its lightness'and the manner in which it is supported,is free to yield readily,if the wagon come in contact with it in passing overuneven ground, and by this means the wagon is preserved from injury. The endless apron, it will be seen, is at the yfront part of the frame A,and in front or most in front of the wheel B, and is driven from the wheel B, as usual. The w'hole device is 'rendered very Vcompact and a machine of light or easy draft obtained.

The reel N has its shaft h tted in proper bearings, and is placed in its usual position over the front part ofthe frame A, as shown in Fig". l, Y

*WeV do not claim, boudly,tlie use of a jointed apron fof conveying and elevating grain in ya. harvesting-machine; `lout We do claim as new and desire to secure by Letters Patent- 1. The elevated yyoke E, connecting lthe linked rear rail, b, of the balanced frame A, and employed in connection with the thrusting-tongue D, rope F, and pulleys c d, substantially as and for the purposes set forth.

2. The endless conveying 'and elevating apron K, carried at one end in an inclined frame, L M, jointed midway of its length in standards g, in the manner and for the purpose herein shown and explained.
